Abstract
Elecampane (Inula helenium L. Compositae) is a perennial plant found in damp medows and shaded areas of central Europe. It is most commonly found in the wild state in Iran. In this research, plan are collected from Hamedan city on west of Iran. Essential oil was extracted from flower by two methods (Steam distillation and Hydrodistillation) and root by Hydrodistillation method.
The percentage of oil from flower 0.07% and root 0.06% are calculated, and analysed by GC and GC/MS. The main components for flower by steam distillation Oplopenone (19.1%), a-Cadinol(5.5%), T-Cadinol(4.9%), S Cadinene (4.5%), and Curdione (4.2%) and by Hydrodistillation Globulol (7.2%), Cadalene (7.0%), S-Cadinene (6.7%), Torreyol (6.1%) and Oplepenone (5.1%). The main components for root by hrdrodistillation are Alantolactone (24.9%), Spathulenol (10.8%), (E-E)-Farnesol (8.1%) and Ledol (7.4%).
